The current Octave 3.4.0 on Fedora 15 is giving me an "out of memory" message when I plot certain data. See example below. It depends on the range, and the particular function. Anyone else get this behaviour?
[code]...
I'm curious if anyone know how to plot stem-and-leaf plot using perl? Basically, what I was wanting to do is read a bunch of numbers from a text file into an array, sort from smallest to biggest, and plot the following (last digit serves as the "leaf", so for example, for the following graph, going down from top to bottom is 7, 7, 12, 13, 18, 18, 23, 25, 27, 27, 27, 27, 27, 27, 28, 28, 29, 59, 30, 31, 31 etc.):

I'm using 64-bit fedora 14 on my desktop. i was using gnuplot, but there was some power failure and my computer got shut down. now whenever i plot anything it freezes after first plot i have to force quit it

Trying to understand the stats above? Perhaps then I could be able to blame something that consumes my memory.
After CentOS5.3 install to /sdb7 partition (on 2nd HD) and using Ubuntu Grub(on 1st HD mbr) to boot CentOS, I get "memory for crash kernel 0x0 to 0x0 not within permissible range" as soon as CentOS starts. I have 2G of ram. The message is on every boot. I've had several other linuxes on that partition without such an error message. Otherwise the OS starts fine. Is the message of concern/import?

View 1 Replies View RelatedI have a simple C program that reads a 1 GB file from disk into memory.The first time I run this program, the process takes several seconds. But if I run this program again immediately after it finishes, the read happens almost instantly. What is going on here?My suspicion is that the operating system is realizing that the data I'm trying to read is still uncorrupted in memory (its been freed but not overwritten), so instead of reading it again, it just gives me the same block. I would really like to know what this process is called, or any Googleable keywords that would allow me to research it.
The reason I ask is because the size of my input data has increased. Now I need to read in a 6 GB file (my system has 12 GB of RAM), but I'm not observing the same behavior with the larger file. Each time I run the program the read takes an equally long time.
I'm running a java program and to debug the program instead of using a debugger I would like to look to the heap and to the bytes in the memory of the process. I was hoping that the pointers would give me a snapshot of a moment of the application. It exists a program that allow us to look to the details of a process and to the memory ram?

View 3 Replies View RelatedI have a mxn matric (which is my simplified way of saying it is RAM with bytes on it) Some of the locations on this metric is filled with some data and some places are empty. The mxn are very big numbers in size. I am trying to make a program so that if a system call wants to write some thing on empty locations on this mxn metric it should be able to do so without any problem. The thing which I want to understand or logic of a data structure is what data structure do you people feel should I be maintaining so that I can allocate the requested space immediately from the above mxn matric when some system call requests for some (k) number of locations from above metrics.
The logic initially I thought was to maintain a hashtable
1bytes requested----------> location 1,location 2,location 3.........location n
2bytes requested----------> location 1,location 2,location 3.........location n
3bytes requested----------> location 1,location 2,location 3.........location n
[code]....
but the problem with above logic is size of the pointers where I will be writing this problem is unsigned 64 byte.So to know location of one free byte if I am maintaining one pointer of type u64 this is not a feasible solution.
A friend of mine asked me to try and recover some photos she deleted by accident on her SD memory card. Normally, I would flip over to my Windows box and do this, but I'm wondering if there is a Linux equivalent to a Windows data recovery program. I'm running Fedora 10.

I've lost my music on the phone, or, it seems it may be there (the correct mass of data), but my phone now tells me there is no music... Can I recover this? And - what is the correct way to unplug a USB unit in Ubuntu? To make it work, and find the phone/drive - I just typed "sudo lsusb" in the terminal, and it found and opened the memory automatically... How should you unmount the USB, and maybe even how do I get my data back?

View 13 Replies View RelatedIt's been a while since I did any kind of graphics programming, but I would like to start learning how to do graphics stuff in *nix. I started reading the GTK+ 2.0 Tutorial, but a) I've only been able to write a small "Hello World" program, and that tested my patience, and b) I'm not seeing anything which allows you to plot a pixel directly. Back before I migrated to Linux, I used the Windows GDI SetPixel() function for plotting pixels sequentially (this was for a small fractal generator). Mostly what I'm asking is if there's any kind of equivalent function in *nix graphics APIs? GTK+? Would I have to deal with SDL/OpenGL?

Last week my server crashed. I'm trying to diagnose the cause.
This is the relevant error message in /var/log/messages:
Code:
I'm assuming that I can conclude, then, that apache/httpd was the cause of the memory leak?
Next, I've been tracking my memory usage. Using top, this is an average memory load level for my server:
Code:
I'd like to confirm if my understanding of this data is correct, because Plesk indicates that my memory usage is only 50% or less. (Though I have read a number of reports indicating that Plesk's measurements are frequently wrong.)
Top says: Of the 2,073,156K total memory, 1,982,572K (95.63%) is being used, 90,584K (4.37%) is free. Of that sum, 421,948K (20.35%) are being used as buffers. Additionally, of the 2,096,472K of Swap, 60K is used, and 887,700K (42.34%) is cached.
My questions: Is my memory actually being 95% used? Or is the buffered quantity (20.35%) not a use of physical/virtual memory? (i.e. is it disk usage?) Does the amount of cached Swap influence the percentage of physical/virtual memory being used?
In other words, who is correct? Plesk says I'm using 40-50% of my memory, whereas top says 85-95%.
I'm running Maverick on an HP dv6 laptop. I tried recording a video via VLC with the machine's 'TrueVision' webcam. The result seemed to lack audio, so I had a look in preferences > sound. The input tab had the mute button ticked, so I unticked it and tried adjusting the level (while realising I was probably just configuring the mic port and not the webcam's inbuilt mics).
Then things turned bad: pointer became sluggish, and changes I made to the level slider took ages to be reflected visually on screen. I queued up a pile of clicks on the 'close' button and went away for a while. On return, I was met with a box inviting me to stop a script with some screen-width-long incomprehensible name, which of course I did.
Now the system's in a state which sees windows missing title bars (tho' not menu bars) and (more problematically) the upper and lower bars on the desktop absent. I issued a hibernate command from the terminal in the hope that on waking the system would be 'fixed', but nothing changed. I tried alt-tabbing to access my open applications and close them gracefully but this command is ignored. I have 'zillions' of apps going with unsaved data and am not sure what to try next. I'd be happy just to be able to task switch to each open prog and exit it gracefully then restart. But my knowledge of the command line is such that your help is required =) .
